leafR: Calculates the Leaf Area Index (LAD) and Other Related Functions

A set of functions for analyzing the structure
of forests based on the leaf area density (LAD) and leaf area index (LAI) measures
calculated from Airborne Laser Scanning (ALS), i.e., scanning lidar (Light Detection
and Ranging) data. The methodology is discussed and described in
Almeida et al. (2019) <doi:10.3390/rs11010092> and
Stark et al. (2012) <doi:10.1111/j.1461-0248.2012.01864.x>.
